"Hot pixels" are something else. These are pixels always on (or off) regardless of settings...

You're describing high ISO noise. Try enabling NR in camera, and if you really want to use the highest ISO settings, perhaps try something like Photo Ninja for effective noise reduction.

I'm not sure Capture NX2 can cope, as I never touch these high settings. And frankly, above ISO 400 to 800 you're beginning to degrade the otherwise fairly fine sensor...

If it's always on, that would be a stuck pixel right? I might be off, though.

The spots I'm talking about are at full brightness, red blue or green, and don't look like typical high iso noise. There is plenty of iso noise too, but it's MUCH more subtle than the hot pixels. I've seen hot pixels on other cameras, but not nearly as many as what in seeing here. I mean, there are thousands of them.
